The honor was bestowed on her by her father, King Michael, but as he was unable to be present for the ceremony, Crown Princess Margarita had the honor of investing her sister with the honor.
The order was established by King Carol I on May 10, 1881.
A dinner at the Elisabeta Palace was held in honor of the Order. Crown Princess Margarita was accompanied by her husband, Prince Radu, and her nephew, Prince Nicholas, and Princess Marie.
Political officials, including the Prime Minister, Victor Ponta, were also present for the dinner and musical entertainment that followed.
